# What is brodmann area?

Different parts of the cerebral cortex are involved in different functions, both cognitively and behaviorally. The Brodmann areas are a way of mapping the cortex and its distinguished functions, pioneered by Korbinian Brodmann, from which the areas are named. Through using Brodmann's areas, the cortex of the brain can be divided into 52 areas which are numbered sequentially. These areas are distinguished by microscopic anatomy through the shapes and types of cells and their connections. Despite controversy about how precise these areas are located, Brodmann's areas are still widely used today. However, some areas have since been subdivided or are only present in nonhuman primates.

# History of Brodmann Areas

Korbinian Brodmann (1868-1918) was a German neurologist who published research on the cortical cytoarchitectonics in many species, including humans. This publication contained what was believed to be the first map of the cerebral cortex based on variations in neural structure. Brodmann (1909) made a detailed study of the cortex, observing the way its layers, tissues, neurons, and other cells varied in structure and size. He identified and numbered different areas of the brains of many mammals, ending some of the considerable confusion in naming parts of the cortex that existed at the time. Before Brodmann's research, some areas of the brain were beginning to be identified, such as Broca and Wernicke's areas. These areas were identified after damage was discovered in these areas, after language deficits were noticed in these individuals. Brodmann's mapping of the brain takes this further and details all the functional areas of the cortex based on gross anatomical features and cortical micro-structures. Brodmann's areas have been widely discussed, debated, and refined throughout the years and remain the most widely known and most frequently used mapping of the cortex.
